We are excited about arthropod saliva!!!

Our main research is focused on the role of mosquito salivary proteins in the transmission of pathogens like Plasmodium, Zika virus and Dengue virus. We study the immune response of human cells (macrophages, mast cells and endothelial cells) against salivary proteins and how they shape clinical presentation of these diseases.

We also  study the antibody response (IgG, IgM and IgE) against arthropod saliva. In our most recent research, we have identified important salivary proteins from mosquitoes, ticks and triatomine bugs that can be used as markers for human-vector contact important to measure risk of disease.

Another important area of research in our lab is the study of the effect of human immune factors (complement proteins and antibodies) on the immune responses against pathogens in mosquito midgut. Our preliminary data suggest that the human complement proteins C5a and C3a induce important changes in gene expression of immune related genes in mosquitoes infected with Zika and Dengue viruses.
